Microsoft has released three new in-house AI models - MAI-Transcribe-1, MAI-Voice-1, and MAI-Image-2 - through its Foundry platform, directly challenging OpenAI's offerings. These models, developed by Microsoft's MAI Superintelligence team led by Mustafa Suleyman, are the first publicly released output from the team's mission to pursue 'humanist superintelligence.' The models claim to outperform OpenAI's and Google's offerings on various benchmarks, marking a strategic shift as Microsoft gains more independence in the AI space after renegotiating its partnership with OpenAI.

Why it matters

This move by Microsoft signals a significant shift in the AI landscape, as the tech giant seeks to reduce its reliance on OpenAI and build its own in-house AI capabilities. The release of these models directly challenges OpenAI's dominance in the field and could lead to increased competition and innovation in the AI market. It also highlights Microsoft's ambitions to become a leader in the development of advanced AI systems.

The details

The three new models released by Microsoft are MAI-Transcribe-1, a speech-to-text model that claims to outperform OpenAI's Whisper and Google's Gemini on various language benchmarks; MAI-Voice-1, a text-to-speech model that can generate natural-sounding audio in under a second; and MAI-Image-2, a text-to-image model that ranks third on the Arena.ai leaderboard. These models were developed by Microsoft's MAI Superintelligence team, led by Mustafa Suleyman, and are now available on the Microsoft Foundry platform. The release of these models comes after Microsoft renegotiated its partnership with OpenAI in September 2025, which gave the company more freedom to independently pursue AI development.

  • In November 2025, Microsoft formed the MAI Superintelligence team led by Mustafa Suleyman.
  • In March 2026, Microsoft hired Ali Farhadi, the former CEO of the Allen Institute for AI, for Suleyman's superintelligence team.
  • On March 17, 2026, Jacob Andreou, formerly a senior vice-president at Snap, took over as executive vice-president of Copilot, freeing Suleyman from day-to-day product responsibilities.
  • On April 3, 2026, Microsoft released the three new MAI models - MAI-Transcribe-1, MAI-Voice-1, and MAI-Image-2.
